ELEVATING-JACK FOR MULTIPLE WIRES AND CABLES.

To all whom it may concern:

Be it known that I, THOMAS J. Corn, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Elevating-Jack for Multiple 'Wires andCables, of which the following is a specification.

My invention is adapted to provide means for reaching or having accessto a broken or impaired wire or cable in a switch board or other similardevice carrying a multiple of wires or cables. To this end, I employ animplement which I denominate a ack, the

- same being adapted to separate opposite sets of contact wires orcables, so as to uncover or otherwise practically expose the broken orimpaired wire or cable, said implement con sisting of a wedge shapedbody and a roller thereon, the same being adapted to be inserted betweensaid rows or sets and permit said body and its roller to contact withthe latter when in turning the body the outer set of wires or cables areraised and so separated from the adjacent ones, when the broken orimpaired Wires or cables are accessible.

It consists further of a fulcrum member on which the jack may besupported and turned when in position. For the purpose of explaining myinvention, the accompanying drawing illustrates a satisfactory reductionof the same to practice, but the important instrumentalities thereof maybe varied, and so it is to be understood that the invention is notlimited to the specific arrangement and organization shown anddescribed.

Figure 1 represents a perspective view of an elevating jack embodying myinvention. Fig. 2 represents a transverse section on line ccw Fig. 1.Fig. 3 represents a head view of the jack in operation. Fig. 4represents a transverse section on line 'yy Fig. 1. Fig. 5 represents aperspective view of the fulcrum member to be employed with the wedge.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings :1 designates a tapering or wedgeshaped bodywhich consisits of the shank 2, the front end 3 of which is pointed, andthe rear end of which constitutes the head 4, the latter having thereinan opening 5 for receiving, if desired, a rod or Specification ofLetters Patent.

the like, for conveniently rotating said body. A portion of the body ismade hollow in the direction of the length thereof forming the chamber 6for purposes of lightness. In the part 3 is a cylindrical shaped recess7, which forms a bearing for the gudgeon 8 on one end of the tapering orconical roller 9, the latter extending parallel with the shank 2, andhaving a gudgeon 10 on its other end, the same having a bearing intherecess 11 in the head 4 of the body 1. Fitted to the head 4 over thegudgeon 10 is the plate 12, which is secured to said head by the screws13, and while retaining said gudgeon and consequently the roller 9 inplace, it may be removed for access to said gudgeon and admit of thedisplacement and restoration of the roller from and to its position. Theside portion of the shank2 occupied by the roller 9 is somewhatdepressed or channeled to receive the same, and the base of said portionhas concave beds 14, 15, and 16 thereon to permit the roller to rotatethereon and form bearings which additionally support the rollerespecially in its rotation. On the side of the shank 2 there is the rib17 which projects laterally therefrom and extends in the longitudinaldirection of the body. In said side and extending into the same adjacent to the base of said rib is the channel 23 for a purpose to behereinafter described.

18 designates a web which rises from the base 20 forming together a footplate or fulcrum 19 for the body 1, said fulcrum having a nose 21 whichis rounded or turned up as at 22 so as to readily enter between cablesor wires in inserting said fulcrum into its operative position, it beingseen in Fig. 2 that the body 1 when also inserted into operativeposition has its underside or sole 24 parallel with the base 20 of thefulcrum 19 as seen in Fig. 2, such operative positions being between tworows or sets of wires or cables 25 where access is desired to a wire orcable in the adjacent rows or sets. Now as the rib 17 of the body restsupon the web 18 said body is rotated on the web say a quarter turn by arod, bar, etc., in the opening 5 or the application of a suitablewrench, when the wall of the recess 23 rides over the top of said weband gradually seats itself therein, thus providing the fulcrum for thebody. As said turning occurs, the roller 9 being eccentric to thelongitudinal axis of the body rises and gently Cfl 1 flat on thecontiguous portions of the underneath row or rear lines or sets of wiresor cables and has its support thereon, it removes the body 1 from saidwires or cables and prevents twisting, distorting or otherwise injuringthe latter, it being noticed also that as the web 18' enters the recess23, and the rib 17 is parallel with said web, the body is preventedfromshifting or slipping from the fulcrum.

When the work is accomplished, the body is turned in reverse directionwhen the outer orfront rows or sets of wires or cables are released andso may lower to normal position. When but slight elevation of the rowsor sets of wires or cables is desired, or light wires or cables are tobe operated upon, the fulcrum member may be dispensed with, the body 1with its appurtenances being suflicient for the purpose.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is 1. An elevating jack of the character statedcomposed of a wedge shaped body,

and a conical roller mounted thereon on a side thereof and'extending inthe direction of the length of said body.

2. In an elevating jack of the character stated, a wedge shaped bodyhaving a pointed end and a head, and a tapering roller on said bodyintermediate of said end and head.

3. In an elevating jack of the character stated, a Wedge shaped body, achannel in the face thereof in the longitudinal direction thereof,concave beds on said channel, and a longitudinally extending taperingroller adapted to occupy said channel and bear on said beds, andgudgeons for said roller mounted in the opposite portions of said body.

41- In an elevating jack of the character stated, a wedge shaped body, alongitudinally-extending tapering roller thereon, gudgeons on saidroller having their bearings in opposite portions of said body and aplate on said body removably retaining the adjacent gudgeon of theroller in position on the body.

5. In an elevating jack of the character stated, a wedge-shaped body, alongitudinallyextending conical roller mounted thereon, a rib projectingoutwardly from said body, and a recess in the body extending parallelwith said rib and entering said body adjacent to the base of the latter.

6. In an elevating jack of the character stated, a wedge-shaped body anda conical roller thereon and a longitudinally extending fulcrum memberhaving a laterally extending web on which said body may turn, said bodyhaving a channel which may be seated on said web.
